DESCRIPTION:Speakers: Simon Billinge (Columbia University)\nAt the heart o
 f materials science studies for next generation materials is an idea that 
 we want to be studying real materials doing real things\, often in real de
 vices.  In practice\, this presents a number of key data analysis and inte
 rpretation challenges because it implies we are studying ever more complic
 ated samples\, often in complex heterogeneous environments and in time-res
 olved operando setups\, and we are interrogating our data for more and mor
 e subtle effects such as microstructures and evolving defects and local st
 ructures. Of particular interest is the study of nanomaterials and materia
 ls structure on different length-scales.  In this talk I will describe var
 ious developments that leverage the latest data acquisition and analysis t
 echniques\, sometimes powered by artificial intelligence (AI) and machine 
 learning (ML)\, that reveal how materials behave on ultra-fast (picosecond
 ) time-scales after being hit with a laser. The material studied is a quan
 tum material with a charge-density wave transition\, but is a model system
  that demonstrates an approach that could be used to study chemical reacti
 on coordinates for real processes in sustainable energy\, environmental re
 mediation\, and health.\n\nhttps://events.saip.org.za/event/249/contributi
